Abstract (en)
[origin: WO9423083A1] A bainite rod wire or steel wire having an excellent workability in wire drawing and a process for producing the same. The wire contains on the weight basis 0.80-0.90 % of carbon, 0.10-1.00 % of manganese and 0.10-1.50 % of silicon; if necessary 0.10-1.00 % of chromium; not more than 0.02 % phosphorus and not more than 0.01 % of sulfur; and the balance consisting of iron and inevitable impurities. Further it has a tensile strength and a drawing rate as defined by the following formulae (1) and (2), respectively (1): TS </= 85x(C)+60 and (2): RA >/= -0.875x(TS)+158; wherein C represents carbon content (wt%), TS represents tensile strength (kgf/mm<2>), and RA represents drawing rate (%).
